我正在将文件移到.on（＆＃39;结束＆＃39;，功能（数据）..

Error: EPERM: operation not permitted, rename 'c:\Users\XXXXXX\Desktop\project\Nodejs\Attachments\00P9000001LiuvWEAR' -> 'c:\Users\XXXXXXX\Desktop\project\Nodejs\00190

 var csv = require('fast-csv');
  var fs = require('fs-extra');
  var attachmentIDs;
  var recordId;
  var dir;
  var dir1;
  var stream = fs.createReadStream('./Attachment.csv')
      .pipe(csv({
          headers: true
      }))
      .on('data', function(data) {
          recordId = data.Id;
          attachmentIDs = data.ParentId;
          dir = './' + attachmentIDs + '/';
          dir1 = './' + attachmentIDs + '/' + recordId + '/';
          if (!fs.existsSync(dir)) {
              fs.mkdirSync(dir);
          }
          if (!fs.existsSync(dir1)) {
              fs.mkdirSync(dir1);
          }
      })
      .on('end', function(data) {
          var oldPath = './Attachments/' + recordId;
          var newPath = dir1;
          fs.rename(oldPath, newPath, function(err) {
              if (err) {
                  console.log(err);
              } else {
                  console.log("Files Moved");
              }
          });
      });
